The broken lines shown in the drawings are for the purposes of illustrating portions of the article that form no part of the claimed design, or for showing the unclaimed environment of the article (e.g. attached to a handheld device such as a smartphone). The unshaded surfaces adjacent to and between solid line and broken line disclosure form no part of the claimed design. The claim is directed to shaded surfaces only. The left side view is a mirror image of the right side view and is therefore omitted. Additionally, the top view is a mirror image of the bottom view and is therefore omitted.
